When uploading images on my web sit i get an error from php about exhausted memory. The error occurs in image.php on imagecreatefromstring function.
Strange Issue #1: i get this error when uploading mid sized images (800x600) or greater, but i have quite enough php ram to upload 800x600 pics since I have 96 MB of php memory.
Strange issue #2: the amount of allocated ram displayed in error messages changes every time from 8 to 40MB:
Fatal error: Out of memory (allocated 14680064) (tried to allocate 2000 bytes) in /hsphere/local/home/masteraccount/pavan.nozonenet.com/wp-admin/includes/image.php on line 149
14680064 = 14MB, but i have 96MB.
I also installed a couple analysis plugins and the memory is actually 96MB; wordpress setting was correctly modified according to this limit.
Strange issue #3: sometimes certain images works fine, sometimes, when uploading the SAME image, i get an error, even 5 minutes later.
